表 6.2. 列出可用的命令行开关
| 关键字 | 描述 |
|---|---|
| $WCREV$ | 用工作副本中最高的提交版本来替换 |
| $WCDATE$ | Replaced with the commit date/time of the highest commit revision. By default, international format is used: yyyy-mm-dd hh:mm:ss. Alternatively, you can specify a custom format which will be used with strftime(), for example: $WCDATE=%a %b %d %I:%M:%S %p$. For a list of available formatting characters, look at the online reference. |
| $WCNOW$ | Replaced with the current system date/time. This can be used to indicate the build time. Time formatting is as described above. |
| $WCRANGE$ | 在工作目录用更新版本范围替换。如果工作目录处于一致的状态，它是一个单一版本。如果工作目录包含混合版本，或者是过时，或者是故意更新到版本，那么这个范围会用象100:200这样的格式来显示。 |
